挥发性有机化合物（VOC）在制药行业中的使用非常广泛，具有很大的风险，因为潜在的有机气体释放对环境和人类健康都有害。含有活性炭（AC）或其他吸附剂的固定床柱选择性地从气体流出物流中去除VOC。然而，由于流速和混合物组成的同时和显著变化，吸附床可以快速和/或不规则地饱和。本文提出了一种动态的，非等温吸附模型的开发和实施，用于研究二元VOC混合物的吸附工业AC床的各种结构和操作条件。一个基于双组分混合物的行为研究（通过多个动态模拟，实验证实和预测公式）的关键参数变化对床性能的影响。理论床性能分析（采用Glueckauf速端）已被用于提供有价值的洞察非等温VOC捕获床操作，清洁和使用的床。
Volatile Organic Compound (VOC) use is extremely widespread in the pharmaceutical industry, posing great risks, as potential organic gas releases are harmful to both environment and human health. Fixed-bed columns containing Activated Carbon (AC) or other adsorbents selectively remove VOCs from gas effluent streams. Nevertheless, adsorbing beds can be quickly and/or irregularly saturated, due to simultaneous and significant variations of flowrates and mixture compositions. This paper presents the development and implementation of a dynamic, non-isothermal adsorption model used for studying binary VOC mixture adsorption on industrial AC beds for a wide variety of structural and operating conditions. A scenario-based investigation of binary mixture behaviour examines (via multiple dynamic simulations, experimental corroboration and predictive formulas) the effect of key parameter changes on bed performance. Theoretical bed performance analysis (employing Glueckauf hodographs) has been employed to provide valuable insight into nonisothermal VOC capture bed operation, for both clean and used beds.
